## Review summary

User reviews indicate the Screamin' Eagle Street Tuner app is unreliable on iOS: frequent crashes and Bluetooth disconnects, poor error-code reading, and flaky tune loading. Firmware updates often worsen these issues. A minority report smooth operation and modest gains when it works, but overall the negatives dominate.

### Pros

- When the app/tuner is functioning, live tuning and gauge data can be usable.
- Autotune can deliver smoother throttle and reported gains (e.g., smoother performance and potential HP/torque increases).
- For some setups, it is an official path to tuning that can preserve the Harley warranty.

### Cons

- Bluetooth connectivity is unstable, with frequent pairings and disconnects
- The app frequently crashes, including during tuning or when viewing gauges
- Error codes/DTC reading is unreliable or non-functional
- Tuning/calibration loading is flaky, often requiring many attempts or failing when renaming files
- Recent firmware updates often regress functionality and introduce new bugs (gauges missing, crashes)
